HENRY'LKELLEY, or KANSAS CITY, MISSOURI.

OIL-BURNER.

` Application led 'March 1, 1912. Serial No. 680,911.

To all whom 'it may concern.: i

Be it known that I, HENRY A, KELLEY,

I a citizen of the United-States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented' certain new and useful Improvements in Oil-Burners, of which the following is a speciication.-

My invention has reference to a burner adapted for the use of liquid fuel, and my objects are to provide a burner of this character wherein maximum eliciency is had with a minimum consumption of fuel; whichcan be readilyt disconnected or taken apart when desired, and which is not liable to clog or become choked when in use.

I n order that the invention may be fully understood, reference will n ow be made to the accompanying drawing, in which:

Figure 1 is a side elevation of my burner. Fig. 2 is a front elevation of the burner. Fig. 3 is a vertical .section on line III- III of Fi 2. Fig. 4 is a horizontal section on kune I Iv of rig. a

In carrying out the invention, I construct the burner of three main parts, namely: a

feed-chamber 1, a mixing-chamber 2, and a discharge-nozzle 3, which parts can be readily assembled ,f or taken apart should it become necessary to `clean said burner. Feedchamber 1 is of conical form and superimposed upon the mixing-chamber 2, it being divided therefrom by a removable partitionI 4 provided at its forward portion with a series of feed-tubes, depending into the mixing-chamber 2 and provided at their rear lower portions with discharge orifices 6. The upper reduced portion of the feedi chamber 1 communicates with a supply-pipe 7, which conducts fuel oil thereto from a suitable source, not shown. Mixing-chamber 2 is circular at its upper portion to receive the circular lower end of feed-chamber 1 and tapers downward and terminates at its forward end in a circular portion 8 provided with coupling 9, whereby it is coupled to the rear circular port-ion of nozzle 3. Nozzle 3 flares forward and has an elongated discharge slot 10 at its forward end.

11 designates a plurality of vertical pins extending through the nozzle 3 and arranged in rows to assist inatomizing the fuelas it passes through said nozzle.

Al2"designates a steam or other fiuid supply-pipe leading from a supply source, not shown, and extending'into the rearportlon vofthemixing-chamber 2, where it terminates in an elongated discharge-slot 13, approximately o n a line with the Alower terminals of the feed-tubes 5. .v

In practice, the fuel oil is supplied tothe feed-chamber 1 preferably under pressure and discharges therefrom through the feedtubes 5 in the direction of nozzle 13, it becoming more or less heated in its passage through the feed-chamber and said feedtubes. As the fuel oil discharges backward through the orifice 6, it impinges against the steam or other -fluid under pressure discharged from the slot 13, which fluid commingles with andatomizes the fuel oil and carries it forward through the mixingchamber 2 and the nozzle 3. from which` latter it is discharged in the form of spray or mist. As the mixture of fuel oil and fluid impinges against the pins 11 in its passage through nozzle 3, said fuel oil is further atomized so that complete combustion results when the miXt-ure discharges from slot 10 and becomes ignited. f

`While I have shown the preferred arrangementand construction of my burner, I do not wish to be confined to the specific arrangement disclosed, but reserve the right -Speciication of Letters Patent. Patented Aug. 2'?, 1912.. i

to make such changes as properly fall within the spirit and scope of the appended claim.

Having thus described my invention what- I claim and desire to secure by Letters Patent. is: s v

A burner consistingof a feed-chamber, means for supplying said feed-chamber with fuel oil, a mixing-chamber connected to said feed-chamber, a partition separating the feed-chamber from said mixing-chamber, feed-tubes depending fromsaid partition into the mixing-chamber and provided at their lower rear.portions with discharge orifices, a discharge-nozzle communicating vwith the forward portion of the mixingchamber, and a fluid supply-pipe projecting into the rear portion of the mixing-chamber substantially 'on a plane with the lower terminalsl of the feed-tubes, for the purpose described.

In testimony whereof I affix my signature, in the presence of two witnesses.
